Phoenix discovers SQL Resources like instances, availability groups (AGs), and associated databases when the Phoenix agent runs a discovery operation. Phoenix runs a discovery operation when:
- A Phoenix agent is activated.
- The Phoenix agent service restarts on the Windows Server host. Phoenix runs discovery only if there is at least a 20-minute gap between two restarts.
- Every 24 hours.
- It is triggered using the Phoenix Management Console and it was not triggered automatically in the last 10 minutes.
- For an AG backup set, you run a backup using the Backup Now button on the Phoenix Management Console.
Note: Phoenix cannot run a discovery on only one node of an AG. For Phoenix to discover databases on an AG, the Phoenix agent should run discovery on at-least two nodes of the AG.
